Want to buy a lens or my 1.6 DSLR. It will be for outdoor portraits exclusively.
I was thinking a 70-200mm but most of the time I see guys using the 24-70 and 24-105 lens for this stuff. What focal range is typically suggested for this type of work?
If my understanding is correct, your question was about focal length range, so I will refrain from giving unwarranted opinions about which lens and stick to focal length range. I use the below focal length ranges from a 8-10ft subject distance for the kind of work you mention:
50-60mm on APS-C captures waist up from 8-10' (4.0' x2.7')
60-70mm on APS-C captures had & shoulders from 8-10' (3.4' x 2.3')
90-100mm on APS-C captures tight headshots from 8-10' (2.3' x 1.5')
Thw shooting area required will work out to 25-26' long shooting area (2.5' backdrop, 5' separation to backdrop, 2' subject, 10' camera-to-subject, 2.5' camera, 3' photographer. If you have more distance (luxurious indoor shooting or outdoors), simply multiply the above FL by the proportional factor (e.g. 20' camera to subject = 2 * FL in above paragraph).
Do not go too short or too long, else you start seeing perspective distortion. For an example, have a look at the link http://www.stepheneastwood.com …/lensdistortion/index.htm
. Although the shots have been taken with a full frame body, but it does not matter.
